This invention relates to stands for the transport of stretchers vfiithpatients) in vehicles of all kinds. ese stands have arms or supportingmembers, on which the bearing members for the stretchers are supportedby means of springs. The invention consists in this, that the saidsupporting members are made in the form of U-shaped stirrups, thesprings being positioned between the limbs of the stirrups. Theinvention further consists of various constructional forms of the stand.

The accompanyin drawing shows difierent constructional orms of theinvention,

Fig. 1 being a perspective view and Figs.

2, 3, 4, 5, 6, 7, 8, 9 and 10'being elevations.

The stand consists of a supporting beam 1 with supporting members 2, towhich by means of springs 3 supportin beams 4 for the stretcher areattached. T e supporting members 2 and struts 5 are capable of beingcfolded against the beam 1 for making the stand more convenientlytransportable when out of use. In the stand shown in Fig. 1, which issuitable for lacing in wagons, the legs 22 are also ma e soras to foldand are capable of being adjusted by means of clamping screws 21.

In accordance with the invention the supporting members 2 are made inthe form of U-shaped stirrups, between the limbs of which the springs 3are located. This saves space and enables the beam 1 to be made as s ortas possible. The springs are also protected between the limbs. Thesupporting members 2 are preferably provi ed with abutments 6 embracingthe springs for preventing the springs and the stretcher (with thepatient lying on it) from swinging outwards while the vehicle is inmotion.

In the stand shown in Fig. 2, which is more articularly suitable forvehicles having si es (for instance lorries), the supporting beam 1 isprovided with fixin stirrups 7 which are capable of being sli on andfixed to the beam 1 (for instance by means of screws 9-in slots 10 inthe beam). The stand is placed with the stirrups 7 on the sides of thevehicle, the distance between the two stirrups being adapted to that between the sides of the vehicle. Each stirrup may be provided with aplate'8 which serves both as a guide for the stirrup on the beam 1 andfor extending the same in the'case of particularly wide lorries). hestirrups are provided with a pressure plate 11 which is pressed againstthe side of the vehicle by means of a clamping screw 12.

Fig. 3 shows a modification of the stand for vehicles having high sides.In order to place the'stand or the stretcher in such a vehicle as low aspossible (for the sake of stability) in spite of the height of thesides, the supporting beam 1 is cranked downwards between the attachingstirrups 7, the stirrup 7 bein thus arranged on the upwardly crankc endsof the beam 1. Instead of this the stirrups 7 may be mounted on pillars27, the lower ends of which are connected to the beam 1. Each stirrup 7may be slidable on the bent over upper end of the pillar oron ahorizontal arm 29 of the same with a sleeve 28, whereby the stand isdclaiipable. of being adapted to vehicles of erent widths.

The stirrup 7 may also be vertically ad justable, the pillar 27 beingfor instance capable of sliding vertically with respect to the beam 1,or the arm 29, as in Fig. 4 forming a separate part which can be up anddown the pillar 27. i

For this purpose the pillar 27 ma be a threaded spindle which 1sjournalle ,so as to be capable of turning in a base part mounted on thebeam.

This base part of thespindle 27 may suitably be constituted bya socket30 supporting the spindle and capable of sliding on the beam 1 and by abase plate 8' with a clamping bolt 9' ca able of sliding in a slot 10 inthe beam. 's makes the pillar 27 capable of being slid horizontally 'andfixed on the beam 1.

Through the fixing stirrups 7 being horizontally slidable on the arms 29and the pillars 27 on the beam 1, it is possible to fix the stand on thewidest and narrowest vehicles.

On the plate 8 or 8' in place of a bolt 9 or 9 two bolts 9 or 9' may beprovided (see Fig. 4 one of which serves the purpose of fixing t e plateandthe other acts only as a'guide.

The stands shown in Figs. 5, 6 and 7 are more particularly suitable foragricultural vehicles (for instance so-called open-spar wagons with twoopen-spar sides .or longitudmal spars).

Accordlng to Fig. 5 the beam 1 is provided with screw spindles 17, 18(with handles), along which pairs of gri ping jaws 13,- 14 an displacedlongitudinally. The stand with the beam 1 is laid transversely acrossthe longitudinal s ars of the vehicle, the relative distance of to twopairs of-jaws being adapted to the distance between the longitudinalspars. The two jawsof each pair are thereupon pressed against the lontudinal spar lying between them, where y the beam 1 is fixed in positionon the vehicle.

According to Fig. 6, to either end of the supporting beam 1 a fixingstirrup or jaw 31 1s pivoted, which is capable of being clamped to thewalls of the vehicle. The jaw 31 ma for this purpose be attached bymeans 0 a hinge 32 to the plate 8" which is ca able of being fixed tothe beam in any suita ble manner, for instance similarly to the plate 8or 8' of Figs. 2 or 4. The jaw may be made in a single piece or mayconsist of two parts 31, 31 the lower ends of which grip thelongitudinal spar and the wall of the vehicle and the upper parts ofwhich are connected together or pressed against one another by means ofscrews 33 and 33'. Through the pivotal connection between the attaching.jaws and the beam the latter may be fixed both to the vertical andinclined walls of a vehicle,

' According to Fig. 7 the beam 1 is provided at either end with a sling19 (made for instance of a chain) which is capable of sliding in a slot20, one end of the sling (or both ends) terminating in a nut. The slings19 on the beam 1-the distance betwfeen which is adjustableare slid overthe longitudinal spars of the vehicle, whereupon the slings areshortened by means of the nuts, in which they press against thelongitudinal spars.

The stands shown in Figs. 8, 9 and 10 are more particularly suitable forsmall vehicles, such as trucks, pit tub and the like.

In the stand shown in Fig. 8 (flat open vehicles) the supporting beam 1is supported on two arms 23 which are capable of swivelling on pillars24 which are arranged so as to be fixed to the flat top 25, for instanceby means of jaws 26. By this means with vehicles of different lengthsthe distance between the beams 1 of the two stands canbe adapted to thelength of the stretcher. In the stand shown in Fig. 9

15, 16 are capable of elngvehicle by means of a stirrup 7 (with aressure plate 12, similar to Fig. 2). In t ese stands the beams 1 may beomitted and the supporting members 2 mounted directly on the arms 23 (ofFig. '9) and be downwardly directed (instead of up wardly). g In thestand shown in Fig. 10 the supporting beam 1 has a groove on itsunderside, which rests directly on the side of the vehicle, so that thestand will project only very slightly over the side of the vehicle.

Thls is of advantage, for instance in low galleries in mines. v

All these stands can be fixed on the vehicles without adapting them inany way and therefore rapldly and in a simple manner.

Instead of the beams 4 hooks 4 may be used for supporting the stretcher(Fig. 2), which are linked to the springs 3 and are provided withsecuring straps 129. The poles of the stretcher are laid into the booksfrom above.

The U-shaped stirrups 2 may be cranked (see Fig. 2 left half),preferably at the place w ere the stretcher support (4 or 4) isconnected to the springs 3. This facilitates the lowerin of thestretcher and placing it in position on the supporting member 4 or 4.

The springs 3 to which the stretcher supporting mem ers (4 or 4) areattached, may be tension springs or compress'ion springs (on which thesupporting members 4 or 4 rest). The beams 1 may be made of wood, ironor any other suitable material.

What I claim is:

1. A stretcher stand including a substantially Ll-shaped supportingmember having opposed limbs, springs suspended between the limbs of thesupporting members, a beam supporting the supporting member, meansadjustable in the direction of the beam for mounting the latter on asupport, said adjustable means including stirrups slidably engaged withthe supporting beam, and slidable connections between the stirrups andsupporting beam.

2. A stretcher stand including a substantially U-shaped supportingmember having opposed limbs, springs suspended between the limbs of thesupporting members, a beam supporting the supporting member, means adustable in the direction of the beam for mounting the'latter on asupport, said adjustable means including stlrrups adaipted to embracethe su port, plates carrie by the stirrups and s ldably engaging thesupporting beam and means adjustably securing the plates to saidsupporting beam. r

3. A stretcher supporting stand includthe pillar 24 is fixed to theframe of the ing main supporting means, a pairof substantiallg U-shapedsu porting members arrange transversely o the mam supporting means andeach having opposed hmbs a. spring suspended between t e limbs of thesupporting members, a stretcher .supporting beam connected with thesprings, and an abutment carried by each of the sup orting members forincreasing the rigi 'ty thereof and for embracing the adjacent spring soas to prevent lateral movement of the supportin beam.

In witness whereo I have hereunto signed my name.
